Integrated Water Resources Management relies on effective and efficient cooperation and coordination among relevant stakeholders. However, water management in Los Angeles is very complex, decentralized, and uncoordinated. There are over 100 water suppliers in L.A. County that use, access or author disparate geospatial data sets. This context creates a barrier to a unified knowledge base on water related information. Improving the spatial and non-spatial data infrastructure upon which water management information is shared would make the current system more transparent and accountable, therefore creating opportunities for better decision-making around water use and other emergent environmental issues.

This presentation envisions an improved Spatial Data Infrastructure in the context of L.A. County water management and suggests some best practices to implement a unified, authoritative, and transparent geospatial knowledge base around water resources. Establishing standards such as numeric identifiers for all water supply entities, and other best practices are discussed.
